You've spent a lot of time asking such questions over the past few weeks. Why not just give Vanguard a call and ask about the options for your company? They're friendly people.

Partly because it is not my company and I don't know how the company has been established. I subcontract through this company, however it is on a W2 basis rather than a 1099. With the recent changes in status at my current client, I don't even know how many people my current company employs any more.

I would imagine these are some of the questions Vanguard or any other firm would ask in order to give details on the available plans.
